Chrysanthemum plant named Guilderland

ABSTRACT

A Chrysanthemum named Guilderland having flat capitulum form and single anemone capitulum type, lavender pink ray florets, and its yellow tinged with pink disc florets.

The present invention comprises a new and distinct cultivar ofChrysanthemum morifolium, hereinafter referred to by the cultivar nameGuilderland.

Guilderland is a product of a planned breeding program which had theobjective of creating new chrysanthemum cultibars with single anemonecapitulum type, pink ray floret color, nine (9) weeks response, and theability to produce commercially acceptable quality in year around cutmum programs. Such traits in combination were not present or neededimprovement in previously available commercial cultivars.

Guilderland was originated from a hybridization made by applicant in acontrolled breeding program in De Lier, Holland in 1980. The femaleparent was Maximo, and the male parent of Guilderland was Show-off.

Guilderland was discovered and selected as one flowering plant withinthe progeny of the stated parentage by applicant in April 1980 in acontrolled environment in De Lier, Holland.

The first act of asexual reproduction of Guilderland was accomplishedwhen vegetative cuttings were taken from the initial selection in June1980 in a controlled environment in De Lier, Holland by a technicianworking under formulations established and supervised by applicant.Horticultural examination of selected units initiated in November 1980has demonstrated that the combination of characteristics as hereindisclosed for Guilderland are firmly fixed and are retained throughsuccessive generations of asexual reproduction.

Guilderland has not been observed under all possible environmentalconditions. The phenotype may vary significantly with variations inenvironment such as temperature, light intensity, and day length. Thefollowing observations, measurements and comparisons describe plantsgrown in De Lier, Holland under greenhouse conditions which approximatethose generally used in commercial practice.

The following traits have been repeatedly observed and are determined tobe basic characteristics of Guilderland, which in combinationdistinguish this Chrysanthemum as a new and distinct cultivar:

1. Generally flat capitulum form.

2. Single (anemone) capitulum type.

3. Lavender pink ray florets.

4. Diameter across the face of the capitulum is 65-75 mm.

5. Pink green cushion (immature) to pink yellow (mature) disc florets.

Of the many commercial cultivars known to the present inventor, the mostsimilar in comparison to Guilderland is the maternal parent Maximo. Incomparison to Maximo, Guilderland has better vigor and lavender pink rayflorets, as opposed to the white ray florets of Maximo. The capitulumform and capitulum type are similar to those same characteristics ofMaximo.

The accompanying photographic drawing shows in front view typicalinflorescence and foliage characteristics of Guilderland, with colorsbeing as nearly true as possible with illustrations of this type.

In the following description, color references are made to The RoyalHorticultural Society Colour Chart. The color values were determinedbetween 11:00 a.m. and 12:00 noon in September 1980 under naturaldaylight at De Lier, Holland.
